About the Suzuki GS400S

A part-by-part application guide for the Suzuki GS400S.

Suzuki Motorcycle Logo

GS400S coverage varies by component. The application table brings the carburetor, pivot and control choices together so a year for one part is not mistaken for coverage across the motorcycle.

Start with the job and the S designation

For carburetor work, distinguish the bowl gasket from the float needle and seat. For chassis work, identify the swingarm pivot or the fitted handlebar control. The table gives the year boundaries; the repair links lead to the corresponding products.

Model and year comparisonGS400S parts differences

Years apply to the part. Check its full fitment and the component fitted to your motorcycle before ordering.

Use GS400E parts or GS400L parts when those suffixes match the motorcycle. The GS400 family comparison includes early base-model parts.

Prepare for the repairIdentify your GS400S components

Keep these details with your repair order.

  1. Record model year, market and the full GS400S designation.
  2. Photograph carburetor markings for fuel-system work.
  3. For a pivot repair, measure the removed bearings and inspect the shaft, spacers and seals.
  4. For a cap, lever or switch, record the fitted mounting and connection details.

Suzuki GS400S parts for repairs & restoration

Choose the repair you are working on, then check the model, year, specifications and package contents on each part before ordering.

Handlebars, mirrors and custom controls

A changed fuel tank, handlebar or control perch can alter accessory fit even when the frame remains GS400S. Compare the installed equipment and steering clearance.

Universal accessories require measurement and may need modification; they are not confirmed direct-fit GS400S parts.

Suzuki GS400S parts questions

Which carburetor parts should I order for my GS400S?
Renew the gasket at the bowl joint; compare its outline with the removed bowl.
What should I check before ordering the float needle and seat for my GS400S?
Select the needle-and-seat assembly for the carburetor’s fuel-entry valve.
Does this repair use the same swingarm bearings for every GS400S year?
The set contains two needle bearings. Use the dimensions in the application table for comparison.
How do I confirm the fitment of the fuel-tank cap for my GS400S?
Select by the filler-neck and locking arrangement, especially if the tank has been replaced.
